You can transfer your progress from one device to another by linking the game to Facebook / Google Play / Game Center account. To do that, go to settings window from drop-down menu and press "Accounts". After that press "Link" under Facebook and input your personal data. If it says "Linked", your account is already linked to Facebook.
On another device make same steps and you will load your game :)
If something went wrong and you lost your account - don't worry! Having detailed information we can restore your game! For more information check out this page :)
Next, repeat this process on your other device. Finally, you can choose your cafe and continue playing from the point where you left off.
